Threaded Piston Valves
Threaded Piston Valve
A threaded piston valve is a threaded gate valve that opens and closes flow by moving a piston between two seal rings. Since the graphite rings provide both seat and stem sealing, no traditional packing leakage is observed; it operates without leakage for many years on steam and high-temperature lines.
Supplied with cast iron body, stainless steel piston and stainless-reinforced pure graphite rings in sizes from 1/2″ to 2″, pressure class PN16. The rings can be replaced without removing the valve from the line.
